For oddball VTs, there is the VT71/t (and its nearly identical twin the VT72) which is an LSI-11 based full file text editing terminal for the Typeset-11 product line.  Also the VT20, the predecessor of that one (perhaps a prototype -- I don't know how many shipped).  That uses an 11/05 as the engine, which drives two independent displays in VT05 cabinets.  I've only seen it once, in the Typeset-11 development lab, tucked in a corner (not running).

BTW, the VT71 is an example of a MOP booted device, loaded via an async serial line.
